Solar Module Introduction
Solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available, based on thin-film cells. These early solar modules were first used in space in 1958.
Electrical connections are made in series to achieve a desired output voltage and/or in parallel to provide a desired current capability. The conducting wires that take the current off the modules may contain silver, copper or other non-magnetic conductive transition metals. The cells must be connected electrically to one another and to the rest of the system. Externally, popular terrestrial usage photovoltaic modules use MC3 (older) or MC4 connectors to facilitate easy weatherproof connections to the rest of the system.

FAQ:
(1)What price for each watt?
It depends on the quantity, delivery date and payment terms.
(2)What is your size for each module? Can you tell me the Parameter of your module?
We have different series of panels in different output, both c-Si and a-Si. Please take the specification sheet for your reference.
(3)Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?
Actually we are only manufacturer of solar panels, but we could try to source them for you in China if you need. We could provide you an optimal system design to instruct you how to install.
(4)Do you have the CE, TUV, UL Certification?
We’ve already passed all the tests, and any certificate is available.
(5)Have you ever sold your products to companies in my country?
Of course, we have customers in all general PV markets, but I think we should expand our market share along with the market growth.
(6)When did your company set up? You are a new company, how can I believe your quality?
We entered into Solar PV industry in 2005, now we have several plants in manufacturing of a-Si and c-Si panels, and our capacity is 220MW per year. Till now we have already passed all the tests by authorized laboratories, e.g. TUV, VDE, UL.
(7)Can you help us install the module if we cooperate with you?
We haven’t entered into installation sector, but we have the plan in near future.

Surely, I will arrange the trip basing on your business schedule.
- Q:i want to charge my mytouch 3g with solar panel(s) it has a 500mah 3.7v 4.4wh batterieswhat do i need to charge it can i use RadioShack 0.5W Solar Panel 4.5V or RadioShack? W Solar Panel 4.5V
- see u have to make ur own ckt for this ur solar panel generate DC if u want to charge ur phine then its convenient way to harge with ur charger for this do this search for net to convert DC-AC convertor since ur charger work on AC so when ur solar panel generate DC it convert into AC that will charge ur phone in ckt u need this thing filter and amp ie the DC voltage come from solar panel 2 DC to AC convertor 3 AMP for AC 4 filter for AC and u are done....... fine ckt from google.....
- Q:Are photovoltaic cells the same as solar panels?
- All okorder
- Q:Are there any safety precautions to consider when installing solar panels?
- Yes, there are several safety precautions to consider when installing solar panels. Firstly, it is important to work with a licensed and experienced professional who is trained in solar panel installation to ensure proper installation and minimize the risk of accidents. Additionally, it is crucial to turn off all electrical power and follow proper electrical safety procedures before installing solar panels. Adequate fall protection measures should be in place, especially when working on rooftops or elevated areas. It is also important to consider the weight and structural integrity of the roof to ensure it can support the panels. Lastly, proper grounding and wiring techniques should be followed to prevent electrical hazards.
- Q:Got a small project here in a remote location. There is to be a 2 volt deep cycle battery, the equipment to be powered from battery and solar panel to charge battery. The 2 volt battery puts out 55 AH. the max constant power draw from the equipment to be powered is 7.9 watts. Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight?And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge?Thanks to all the input!

- Q:My Grandfather just purchased a cheap solar panel kit for his ranch that could not muster enough power to run his mini fridge.He has two 6 volt batteries running positive to negative and would like to add more batteries. Probably 2volt. How would he go about hooking up the other batteries and what kind of wire or coil should he use.Also, I saw on youtube a guy recommending a lead-acid battery from walmart for under $20. I was just going to go to ecology and just pick up some used batteries but I may be wrong.Any help for a first timer might help me and my gramps out will be appreciated.Thank you
- Sorry, I can't really help you :[ Google some stuff, look for help from people who know what to use. If I were you, I'd go with the lead-acid battery.
- Q:The voltage and power problems of solar panels
- In general, the charging voltage is 1.5 times the battery voltage as well, that is 12V battery pack, select the 18V solar panels just.
- Q:What is the purpose of solar panels?
- The purpose of solar panels is to convert sunlight into usable electricity, providing a renewable and sustainable source of power for various applications.
- Q:Has anyone actually used those kits online like energy4green or earth4energy to build their own solar panels or windmills? I'm so tempted but with my budget can't afford to waste any money. They have a 60 day money back policy but that doesn't include the money used to buy the supplies to try and build the things. My electric bill is almost $300 a month due to my stay at home disabled veteran husband who went from Utah snow to Florida sun and he has to have the AC on really cold. If anyone has actually built one can you tell me of your experience and if it actually is worth the money? I do lots of D.I.Y. projects but am a novice with electric besides installing a ceiling fan and changing out a light switch.
- Electric panels are not feasible for most people. They are two super thin layers of polarized material. When the sun hits them electrons move from the first to the second layer with an amount of force. You can't duplicate that at home. What you could do is setup solar heating panels and run them against a Stirling engine. This technique is typically more efficient than normal electric panels anyway in industry. They have heat on one side and cold on the other to generate force. Hook that to any generator to produce electricity. If you are successful building a home system, blog about it, others will want to know precisely how you did it.
- Q:Can solar panels be used for charging electric scooters?
- Yes, solar panels can be used for charging electric scooters. By connecting the electric scooter to a solar panel system, the sunlight energy is converted into electricity, which charges the scooter's battery. This eco-friendly and sustainable method of charging can reduce reliance on grid electricity and promote renewable energy usage.
